The role does not own applications and does not manage people. Success depends on the candidate's ability to understand how systems work together behind the UI, design end-to-end test strategies, and explain how and why data flows across the enterprise. - The ideal candidate has deep functional testing experience across frontend channels, APIs, middleware, core banking systems, real‑time and batch integrations, and understands Canadian banking and/or credit card ecosystems. - This is not a UAT Lead role and not a siloed application QA role. Purpose of the Role - Validate that end‑to‑end business flows work correctly across multiple systems - Design and lead E2E functional test strategies, not just test execution - Ensure data integrity, integration correctness, and downstream impacts - Provide visibility into system behavior behind the scenes, not just UI validation Key Responsibilities End‑to‑End Functional Test Leadership - Lead and execute E2E functional testing across 10+ integrated systems within Retail Payments and Credit Cards - Design risk‑based end‑to‑end test strategies focused on critical business flows (onboarding, payments, settlements, reporting) - Validate data flow across UI → APIs → middleware → core banking → downstream systems - Explain how systems interact and what happens behind the scenes when customers take actions in digital channels - Identify, manage, and escalate environment gaps, test data gaps, and integration issues Integration & Data Validation - Validate real‑time integrations (latency, retries, failures) and batch-based processes (file drops, schedules, reconciliation) - Perform backend validation using logs, APIs, databases, and reconciliation checks - Validate contract behavior, message events, and cross‑system data consistency Cross‑Team Coordination - Coordinate testing across multiple application teams without owning any single system - Partner closely with solution architects, developers, BAs, and SMEs - Ask "why" questions when requirements lack architectural clarity - Clarify assumptions and adapt test strategies as solution understanding evolves Quality & Risk Focus - Design test scenarios tied to customer impact, financial exposure, and regulatory risk - Perform root cause analysis and articulate business relevance of defects - Maintain clear documentation of flows, dependencies, and known failure points Required Qualifications Core Experience - 5+ years in End‑to‑End Functional Testing within banking, payments, or credit cards - Proven experience testing complex, multi‑system integrations without application ownership - Strong understanding of: - Frontend channels (mobile/web) - APIs and services - Middleware and integration layers - Core banking and card platforms - Downstream reporting and data stores - Experience with Canadian Credit Cards and/or Payments systems Technical & Testing Skills - Ability to interpret solution architecture diagrams - API validation experience (Postman or similar) - Backend validation (SQL, logs, traces) - Experience testing real‑time vs batch processes - Hands‑on functional testing (not purely coordination) - ALM / JIRA / Confluence experience - TSYS or similar card platform experience Nice to Have - Exposure to API automation - CI/CD familiarity How Success Is Measured - Can clearly walk through an end‑to‑end banking flow, explaining systems and data movement - Understands dependencies between systems, not just screens - Designs test strategies, not just test cases - Validates integrations even without system ownership - Proactively seeks architectural clarity when documentation is weak Interview Signals (Embedded Expectation Setting) Strong Candidates Will: - Describe UI → API → core → downstream flows - Explain data movement, not just user actions - Differentiate real‑time vs batch testing approaches - Tie test scenarios to business and risk impact - Demonstrate curiosity about architecture and integration behavior Red Flags: - Only talks about screens or scripted test cases - Cannot explain where data goes after the frontend - Treats real‑time and batch testing the same - Relies solely on documented requirements - Assumes integration validation is someone else's responsibility EEO Employer Apex is an Equal Employment Opportunity/Affirmative Action Employer.
